Such a sign is often found in computer games, films, on various kinds of stickers and stickers. It looks quite impressive, attracts attention. It looks bright and interesting, causing certain associations.
He appeared relatively recently, in 1946, in Berkeley. After the study of radiation began, scientists quickly came to the conclusion that it was life threatening. "Invisible death" was to receive its sign. With the help of a bright and easy to remember image, it was necessary to convey the threat that it carries.
If you try to remember and portray this icon from memory, most likely something remotely similar will come out. The chances of success depend not only on the experience of the artist. It is unlikely that someone without any clues will be able to draw the sign of radiation the first time. How to do it right?
Proportions
It would seem that an ordinary circle, inside of which triangular petals are visible. It is not that simple! It turns out that there are certain proportions, based on which even a novice artist will easily draw this image.
You can estimate everything mentally and arbitrarily depict it from memory, but if you need an accurate picture, then it will be most convenient to do this in stages.
The sign of radiation is not so difficult to draw. This will certainly help the compass.
Dimensions
The modern version is a black sign on a yellow background. The proportions of the figure are the central circle of radius R, three petals with an internal radius of 1.5 · R and an external radius of 5 · R, the petals are 60 ° apart.
When rendering, these parameters are used. Of course, you can do everything approximately “by eye”, but then there is a real chance to lose the recognition of the sign, limiting yourself to just a slight external resemblance to it.
If there is a pair of compasses, a protractor and enthusiasm, then it's time to get down to business.
How to draw
- The radiation sign can be of any size, but for convenience, you can take the diameter of a large circle (the outer borders of the petals) equal to 10 cm. With these parameters, it will be quite easy to scale smaller sizes of circles.
- From the same center, it is necessary to draw (without strong pressure) two small circles. With a diameter of 10 and 15 mm. This is the boundary of the inner circle and the edges of the petals-triangles.
- The horizontal line through the center of the circle will become the bottom edge for the two upper petals.
- Using a protractor, you need to measure exactly 60 degrees, drawing the two remaining lines that form the edges of the triangles.
- Excess contours need to be erased and you can start painting.
Traditionally, it is depicted in black and yellow, but the color can vary from lemon to almost orange, depending on the chosen shades.
All! The radiation sign is ready! Simply and easily!
